The purpose of this study is to develop and validate a scale for measuring digital literacy by identifying the factors consisting of digital literacy and extracting items for each factor. Preliminary items for the Delphi study were developed through the analysis of previous literature and the deliberation of the research team. As a result of two rounds of the expert Delphi study, 65 items were selected for the main survey. The validation of the items was carried out in the process of exploratory and confirmatory factor analyses, reliability test, and criterion validity test using the data collected in the main survey. As a result, a 4-factor structure composed of 31 questions(factor 1: digital technology & data literacy- 9 questions, factor 2: digital content & media literacy- 8 questions, factor 3: digital communication & community literacy- 9 questions, factor 4: digital wellness literacy - 5 questions) was confirmed. Also, the goodness of fit indices of the model were found to be good and the result of reliability test revealed the scale had a very appropriate level of Cronbach's alpha(α=.956). In addition, a statistically significantly positive correlations(p<.001) were found between digital literacy and internet self-efficacy and between digital literacy and self-directed learning ability, which were predicted in the existing evidence, therefore the criterion validity of the developed scale was secured. Finally, practical and academic implications of the study are provided and future study and limitations of the study are discussed.

The present study was aimed to investigate the effects of the application of pulsed electromagnetic fields on the blood components associated hyperlipidemia, antioxidant enzymes and reactive oxygen. The subjects were divided into three groups: General Diet, High fat Diet, High fat diet and pulsed electromagnetic fields. Pulsed electromagnetic field was applied with pulsed electromagnetic energy therapy equipment. The Glucose, free fatty acids, triglycerides, cholesterol and insulin was used to measure hyperlipidemia-related blood components, and the GSH, GRD, XO and MDA was used to measure antioxidant enzymes and reactive oxygen. The applied pulsed electromagnetic field has improved the concentrations of blood components and increasing GSH and GRD, that were decreased due to a high-fat diet and by reducing the increased MDA and XO to a level of general diet group. Therefore, the applied pulsed electromagnetic field can be the effective treatment for changes in the blood composition of hyperlipidemic rats, enhancement of antioxidative activity and the inhibition of reactive oxygen.

Population aging in Korea is in progress rapidly, though it isn't recognized as a critical situation now. Absolute scale of population will decrease since 2030 and that of 2050 will stay in 2005 levels. But most serious problem is that the core working age group, 25-54 ages will begin to decrease since 2012 because of low fertility and population aging. In these situation of population aging, we will face inevitably great amount of labor force shortages and we should build up policy alternatives for solving these problems. I proposed some policy alternatives. firstly, pronatalism policies including state-supported child-care system for preventing decreases of absolute scale of population. Second, facing up to labor shortages under population aging, I proposed policy alternatives for increasing labor market participation, measured by employmeny rate, of aged (or aging) people including wage-peak system of extending retiring ages and women including lowering opportunity costs of women labor market participation rates, given laboer forces. And to conclude, we should approach to the aging problems by steady state equilibrium ecnomic growth, under inevitable population aging.

Documentation strategy has been experimented in various subject areas and local regions since late 1980's when it was proposed as archival appraisal and selection methods by archival communities in the United States. Though it was criticized to be too ideal, it needs to shed new light on the potentialities of the strategy for documenting local regions in digital environment. The purpose of this study is to analyse the implementation issues of documentation strategy and to suggest the directions for documenting local regions of Korea through the application of the strategy. The documentation strategy which was developed more than twenty years ago in mostly western countries gives us some implications for documenting local regions even in current digital environments. They are as follows; Firstly, documentation strategy can enhance the value of archivists as well as archives in local regions because archivist should be active shaper of history rather than passive receiver of archives according to the strategy. It can also be a solution for overcoming poor conditions of local archives management in Korea. Secondly, the strategy can encourage cooperation between collecting institutions including museums, libraries, archives, cultural centers, history institutions, etc. in each local region. In the networked environment the cooperation can be achieved more effectively than in traditional environment where the heavy workload of cooperative institutions is needed. Thirdly, the strategy can facilitate solidarity of various groups in local region. According to the analysis of the strategy projects, it is essential to collect their knowledge, passion, and enthusiasm of related groups to effectively implement the strategy. It can also provide a methodology for minor groups of society to document their memories. This study suggests the directions of documenting local regions in consideration of current archival infrastructure of Korean as follows; Firstly, very selective and intensive documentation should be pursued rather than comprehensive one for documenting local regions. Though it is a very political problem to decide what subject has priority for documentation, interests of local community members as well as professional groups should be considered in the decision-making process seriously. Secondly, it is effective to plan integrated representation of local history in the distributed custody of local archives. It would be desirable to implement archival gateway for integrated search and representation of local archives regardless of the location of archives. Thirdly, it is necessary to try digital documentation using Web 2.0 technologies. Documentation strategy as the methodology of selecting and acquiring archives can not avoid subjectivity and prejudices of appraiser completely. To mitigate the problems, open documentation system should be prepared for reflecting different interests of different groups. Fourth, it is desirable to apply a conspectus model used in cooperative collection management of libraries to document local regions digitally. Conspectus can show existing documentation strength and future documentation intensity for each participating institution. Using this, documentation level of each subject area can be set up cooperatively and effectively in the local regions.

The ongoing COVID-19 pandemic has led to a widespread shift towards non-face-to-face/uncrewed services in various sectors of society. Despite this, research on the digital divide has focused predominantly on analyzing various factors, with the notable absence of studies addressing the digital divide. Therefore, study examined the current digital divide in the transportation sector through a survey-based approach. First, a nationwide survey was conducted among adult men and women to assess their digital device usage. Vulnerable groups sesceptible to digital disparities were identified based on factors such as age, education, and income. Second, comparative analysis was conducted to examine the usage patterns of mobile applications related to the transportation sector among the vulnerable and non-vulnerable groups using chi-squared test. These findings suggest that the vulnerable group exhibited lower awareness and preference for mobile applications, a significantly lower frequency of application usage than the non-vulnerable group. Finally, a comparison of the proficiency in utilizing transportation sector mobile applications was conducted, showing that the vulnerable group demonstrated a significantly lower level of proficiency across all aspects of application usage procedures compared to the non-vulnerable group. These survey results provide a valuable foundation for future policy formulation to reduce the digital divide in the transportation sector. By highlighting the current state of digital disparities, the research contributes to developing evidence-based strategies to enhance inclusivity and equal access to digital services in tjwtransportation.

In the modern era, the necessity of color capability in the digital era is the demand of the era, and research on improving color practice on the subdivided digital four areas that are not in the existing practice is needed. For digital majors who are difficult to solve in existing paint color practice, classes in digital color practice in four more specialized areas are needed, and the use of efficient artificial intelligence was studied for classes in digitized color and color sense. In this paper, we tried to show the expansion of the color practice area by suggesting digital color practice and color matching method based on Photoshop artificial intelligence and big data technology that existing color and color matching were practice that only CMYK could do. In addition, based on the color quantification data of individual users provided by the latest Adobe Sceney program artificial intelligence, the purpose of the practice was to improve learners' predictions of actual color combinations and random colors using filter effects. In conclusion, it is a study on the use of programs that eliminate ambiguity in the mixing process of existing paint practice, secure digital color details, and propose a practical method that can provide effective learning methods for beginners and intermediates to develop their senses through artificial intelligence support. The Adobe program practice method necessary for coloration and main color through theoretical consideration and improvement of teaching skills that are better than existing paint practice were presented.

미래사회를 대비하기 위하여 7차 교육과정에서는 창의력과 문제해결력 신장을 그 목표로 하고 있다. 그러나 학교에서의 컴퓨터 교육과정은 지나치게 기능 위주의 내용이나, 단순 컴퓨터 활용교육만을 강조하고 있어 이러한 취지를 잘 살리지 못하고 있다. 이와 같은 문제를 해결하기 위해 컴퓨터 프로그래밍에 대한 관심이 점점 증대되고 있다. 컴퓨터 프로그래밍은 그 자체가 문제 해결 과정을 포항하고 있기 때문이다. 그러나 프로그래밍을 초등학생들이 배우면서 프로그래밍의 기초인 이진법과 이진연산을 쉽게 이해하지 못해 어려움을 많이 겪고 있다. 게다가 이진법은 디지털화의 중심기술로서, 향후 미래사회를 이해하는데 매우 중요한 부분으로 자리 잡아 그 자체로도 큰 중요성을 가지게 되었다. 이에 본 연구에서는 학생들 수준에 맞춰 프로래밍의 기초와 이진법, 이진연산을 학습할 수 있는 교육 방안을 개발하기 위해 'LED 소자를 이용한 프로그래밍의 기초교육 방안'을 설계하여, 고차원적인 문제해결력과 창의성을 기르는 컴퓨터 교육의 한 모델을 제시하였다.

This paper proposes ADAPTIVE STOCHASTIC ITERATION ALGORITHM that can be used for the full-duplex digital data transmission over existing twisted-pair cables. The canceller step size changes according to the residual echo level. Thus convergence speed increases by an order of magnitude over the conventional stochastic interation alogorithm. And it can be combined with the sequential type adaptive digital filter that simplifies the conventional echo canceller circuit. Thus it is suitable for LSI implementation. Theoretical analysis on two algorithms is carried out and the algorithm simulation program is developed.
